摘　　要：扬州头桥水厂向市区供水的一根PCCP管道(DN1600)铺设在S356省道北侧,管道上方为绿化带。2018年施工的五峰山过江通道公路接线工程WFS-3标段与S356省道交叉,交叉路口占用部分绿化带的位置,管道上方的荷载发生变化;采用盖板箱涵保护管道,管道原位不动,管道上方的路面荷载通过盖板及涵台传递到地基上,管道不受地面荷载的影响,而且管道原位保护采用盖板箱涵方案具有足够的安全储备。这种盖板箱涵保护管道方案的设计与施工可操作性强,具有可复制推广价值。A DN1600 PCCP pipeline for Yangzhou Touqiao waterworks to supply water to the urban area is laid on the north side of S356 provincial road,and the green belt is above the pipeline.The WFS-3 section of the highway connection project of the Wufengshan river-crossing channel constructed in 2018 intersects with the S356 provincial highway.The intersection occupies part of the green belts,and the load above the pipeline has changed.The pipeline is protected by cover plate box culvert in-situ,so that the pavement load above the pipeline is transmitted to the foundation through the cover plate and culvert platform.The pipeline is not affected by the ground load,and the cover plate box culvert scheme for in-situ protection of the pipeline has sufficient safety reserve.The design and construction of the cover plate box culvert are operable and can be replicated and promoted.
